To call this a nice view, is to describe the ocean as a bit humid. The sun sets into the ocean in Santiago. As a result, the Andes are bathed in the most magnificent light of the day during sunset. From it's high perch, there is very little to obstruct the view. The room is cozy, clean and modern and gets the Santiago sun in the AM, and a great patio for sunsets.
Otherwise, the apartment and Carla and Katty were a joy a deal with - and made life easy.
The neighborhood is bustling outside till the wee hours. In the center of Santiago, Baquedano undergound metro is within a few blocks. There are parks near by. Which make the city runnable... We rented this place for a month, and used it as a base to explore all of Chile. I'd do it again.
If you need tour advice, see the boys at infotour - it's very close, and they can fix you up with anything you need.

We stayed in 4 people at Katty`s apartment during 9 days, and the location is great! Close to a lot of bars and restaurants, to the Baquedano metro station, Cerro San Cristóbal, museum of fine arts and Pablo Neruda`s house La Chascona.
But, as we were there during the summer, it was really hot and sunny all day, even if we closed the bedrooms curtains, by morning with sunrise we couldn`t sleep later than around 8am. There is no air conditioning, and, unfortunately, we only found the second fan when we were packing to leave - it wasn`t showed to us on check in by the person Katty sent. At night we slept with the bedroom`s window opened and that way we could hear the noise of the active nightlife of the region.
The smaller bedroom is too small for two, not impossible to sleep, but uncomfortable.
The place is a little different from the pictures, like some furnitures, but nothing big.
The kitchen is nice, it has equipment and utensils needed; the oven stopped working until we found what was wrong and fixed it when needed.
The bathrooms are good and clean, the negative thing was we only got 1 small bathroom towel and 4 big bathroom towels for 4 persons using 2 bathrooms for more then a week.

We stayed 20 days in Katty apartment. It was a very pleasant stay. The apartment is very nice and has the necessary things for two persons - including washing facilities below and a sunny pool. Location is very good as well - close to bars/restaurants and metro. Katty was very nice and flexible and our communication was good and quick. Very recommendable.

I never met Katty but the apartment she rents out is great! The view is great, the wifi is pretty snappy, the kitchen is neat and clean. Her cousin next door, who left me in, is really sweet.
The fire alarm gets pulled a bunch in the apartment building -- it happened three times while I was there. If you're used to North American building codes, you'll find it a little jarring when you realize that there's no fire escape.
The neighborhood is a little loud at night, but if that's problem (it shouldn't be) don't stay in Bellavista.
I mention the two things above in passing, overall this is a hearty recommendation.
